Natural ventilation is among those effective methods that is useful in hot dry climates. One of its important uses is in the atrium spaces in the office buildings. Although, as a passive solution, it has a significant impact on the reduction of energy consumption, the control of inlet and outflow of air as well as the control of air current temperature has always been a challenge for architects...

the first step in evaluating the visual performance and energy efficiency provided by daylight, requires an accurate estimation of the amount of daylight entering a building. the atrium concept allows the exploitation of daylight by bringing natural light into the center of the buildings, thus enhancing even a more distribution of daylight. daylight reception through an atrium is particularly b...

This paper presents a methodology for optimizing skylight design with the considerations of thermal comfort, daylight availability and energy performance by integrated daylight and thermal simulation. Dynamic thermal modelling programmed IES and daylight simulation engine Radiance are used as simulation tools to study energy performance of a shopping mall atrium with a skylight on the roof ...

Meticulous planning is required to minimize heat-stress conditions in barns. The objective of this study was to determine optimum barn characteristics for high-yielding dairy cows under Israeli (Mediterranean) summer ambient conditions, by using a new stress model that takes ambient temperature, relative humidity and wind velocity into account. During the summers of 2004 and 2005, three meteoro...

The paper describes a novel approach for the generation of 3D building models from airborne laserscanner data, which is based on the detection of straight lines in specific 2D projections of the data. First, the main roof ridge directions of a building are determined. Based on these ridge directions, hypotheses on the roof orientation are generated. The whole point cloud is rotated by the roof ...

After reisolation of reconducted PVs (left superior, right superior, and left inferior PVs) and completion of making a roof line (posteriorly to the roof vein), a Lasso catheter (meas...

With the development of urbanization, more and commercial buildings are built in cities, which is resulting a large amount building energy consumption that threatens ecological environment earth. Lighting occupies proportion consumption, improving quality natural daylight atriums great significance for efficiency as well indoor comfort. This paper proposes method optimizing atriums. Starting fr...

Methods and results We report here with a case corresponding to the above disease entity, in which pulmonary veins were drained into a separate posterior chamber, which was connected to the common atrium, thus forming cor triatriatum. A 42-yearold Asian female was consulted for operation of p-ECD and PLSVC, which were detected during the evaluation of complete heart block. She complained of wor...

OBJECTIVE The present study aimed to evaluate a new method for validation of complete linear block at the left atrial (LA) roof. BACKGROUND Linear lesions at the LA roof have been reported to improve the success rate of catheter ablation of atrial fibrillation (AF). METHODS Complete linear block at the LA roof was evaluated in 31 patients after complete isolation of pulmonary vein antrum (P...
